Land use and climate changes effects on plant and soil C and N dynamics

Soil is the major terrestrial reservoir of C. In spite of its obvious importance, there is a lack of knowledge about how climate change and land-use change interactions affect carbon cycle. The aim of this research line is to contribute to assess the vulnerability of soil carbon stocks in silvopastoral systems, by means of understand the mechanisms underlying soil carbon processes under different land uses and climatic change scenarios.
